Sergio is a taxi driver in Naples. Under an incessant downpour of rain, he ferries his customers around a city that looks ever more dilapidated and depressed. At the same time he is trying to come to terms with the death of his brother who had gone to Tibet ten years before and never came back. Among the passengers who come and go are a singer, a radio presenter, an old uncle and other characters who each bring reminders of the departed brother. And so Sergio drifts, borne away by taxi and memories as well as the music he made with his brother. But then he sits at the piano and starts to express his feelings in notes he had given up for lost.
